Booltool addon not punch a hole
Bool Toll fail
In provided file the Bool Tool, brush type Difference, works for me.
But your screen of &quot;helmet&quot; object looks differently. On screen Mirror modifier has unchecked Merge, so if you used it in this condition - Bool Tool failed.

Missing Canvas menu
This menu appears only when a brush is used. Than you can see properties menu when &quot;Canvas&quot; object is selected. BTW you have selected &quot;Brush&quot; object. So when boolean operation is used also here &quot;Brush&quot; properties appears when selected.
